BALTIMORE (AP) — A D.C. man has pleaded guilty to robbing a Queenstown diamond store of more than $362,000 worth of engagement rings.

Forty-three-year-old Roy Lee Tolbert entered the plea last week in federal court in Baltimore. He faces a minimum of seven years in prison at sentencing on Dec. 17.

According to information presented in court, on May 19, 2013, Tolbert entered the store wearing a ball cap, wig, fake beard and sunglasses. Prosecutors say Tolbert pointed a handgun at the store’s employees and demanded diamonds in a display case.

Authorities say employees gave Tolbert about 60 diamond engagement rings, which he into a backpack he was wearing on his stomach.

Prosecutors say Tolbert fled, but was identified by DNA found on the fake beard, which he discarded after the robbery.
